COMPLETE -Tremopanation - Lovetone Wobulator build thread (was: Teasing is fun!)

This is completely unverified at all at the moment.



It's also waiting on parts.

[billstein]

I don't know what it is I just know I need it.

[rullywowr]

Verah nice!  I'm gonna go out on a limb and guess that it's a panning/dual tremolo

[midwayfair]

I expect we'll all have to await the reveal with trem-pedation.

I expect we'll all have to await the reveal with trem-pedation.

I am sure everybody will get a little shaky.

You pan-heads are so funny!

I'm wobbling with excite!

[LaceSensor]

heres hopping the wobbles dont tick

[Govmnt_Lacky]

Alan... you have been on a tear lately with the fabbed projects! Exciting stuff!!!!

Im shaking over here!!! 

[juansolo]

Impressive!

I don't know what it is I just know I need it.

hahah + 1 here for the junkies!!!

The Tayda bag turned up





And (after a brief bout of "what the hell is wrong") I now have a trem that trems

Some rising and falling hissing with the envelope, no ticking that I can notice. I did separate grounds (gnd and siggnd), which are only connected at the ground at the test box. The expression pedal wires are not right, I only got a non-fastest speed when I clipped the loop of wire open, and the rate pots are on the wrong sides (I'll change them from pcbmount to wired when I box it, and put them on the correct side.) The two DPDT switches are my temporary testing "stomp" switches. They'll get swapped out when I box this.

I also can't remember what the hell the Mode rotary does. (One is Dual, the rest have the second side's LFO slaved to the first side.) The Shape one is obvious, you can tell from when the LEDs go from triangle to square I didn't include the little signal transformers, I will when I box it up. They're for some kind of isolation, to avoid ground issues when you're running in stereo, I think. I don't think I'll bother with the Trig and Expression jacks when I box it. My guess of 20k/2M LDR seems to work okay. The second LFO is decidedly slower than the first, probably since it uses a 2u2 cap instead of a 10u cap. I think I'll leave it at that, for now.

Sorry for the stream of consciousness. I've got to go to music practice at church in twenty minutes.

And for those who didn't guess, the Tremopanation 0.3 is a copy of the Lovetone Wobulator from MarkusW's schematic.

If you continue to flood the place with wobbling devices I may actually start thinking I also may need something like this.



You are doing a tremendous job getting this stuff to work!

[LaceSensor]

Wild!

Spent a bit more time with it this morning.

The expression jack is now working -- it differs from the Doppelganger in that the jack does NOT use the switching terminals -- with no expression pedal plugged in, the connection between tip and screen should be open. Works best with a high impedance volume pedal, rather than a expression pedal (not enough range.) Looks like this, and the Trigger, will be making it into the final box after all. It also means you can slow the LFO down beyond what it will normally do.

Had it plugged into the Haast's to get the stereo sound into my headphones (for good separation, plus the flatmate is sleeping last night off.) Worked well. Went to get my two wallwarts, then it dawns on me... "Why am I bothering with those and a power strip when my Cioks AC10 turned up yesterday?!" (Good thing the FV500H turned up as well!)
